It is the policy of OMEGA Engineering, Inc. to comply with all worldwide safety and EMC/EMIregulations that apply. OMEGA is constantly pursuing certification of its products to the European NewApproach Directives. OMEGA will add the CE mark to every appropriate device upon certification.The information contained in this document is believed to be correct, but OMEGA accepts no liability for anyerrors it contains, and reserves the right to alter specifications without notice.WARNING: These products are not designed for use in, and should not be used for, human applications.

The OM-EL-WiFi-TH sensor measures the temperature and humidity of the environment in which it is situated. Data is transmitted wirelessly via a WiFi network to a PC and viewed using a free software package. During configuration the sensor will search for an existing wireless network while physically connected to the PC. It can then be placed anywhere within range of the network. If the sensor temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application (max 60 days at 10 second sample interval). The range of the sensor can be increased by using WiFi extenders.

This OM-EL-WiFi-TH is a low powered battery device. When configured using typical sampling periods (e.g. once every 60 seconds) the sensor will operate for over one year. The battery can then be recharged via a PC or USB +5V wall adapter using the USB lead provided.

The battery is safely charged when the unit is operating between 0 to +40°C (+32 to +104°F). It is protected against charging outside this temperature range. Sensor readings may be inaccurate during battery charging.

The software installed on the PC will allow set-up, data logging and data review. Set-up features will include sensor name, °C/°F, sample rate, and high/low alarms. Once configured, historic data can be viewed via the graphing tool or exported into Excel. This software is available for free from www.omega.com.

LCD SCREEN SHOTS

ADDITIONAL FUNCTIONALITYWhen the user cycles through to the Recieved Signal Strength Indicator (RSSI) screen the unit automatically transmits a dummy message every 2 seconds to enable an RSSI reading to be displayed. If there is any outstanding data waiting to be transmitted, this data will be sent at the same time but if not it’ll just send the dummy message and the next data package will be sent as per the unit configuration.

When on Max or Min screen, holding the button for 3 seconds will clear the stored values.

The sensor can be restarted by holding the button for 10 seconds until the screen blanks and LOW is shown flashing in the top right hand corner of the display. The sensor will retain all settings but will lose any data that has not been transferred to the PC. The sensor can be reset to factory state by holding the button for 20 seconds but this will delete all settings and stored data.

Note: neither the restart or the reset will delete data already transferred to your PC.
